Moreover, the invention relates to processes and intermediates for preparing compounds of the formula I, to compositions comprising them and to the use of these derivatives or of the compositions comprising them for controlling harmful plants.

3-phenyl-substituted isoxazolines are known from the literature, for example from EP 514 987. EP 334 120 discloses isoxazolines which are substituted in the 3-position by an unsubstituted heterocycle. Furthermore, JP 2001/158787 describes 3-pyrazolyl-substituted isoxazolines. WO 02/19825 and KR 2002/19751 disclose thienyl-substituted isoxazolines. JP 09/143,171 mentions isoxazolines which are substituted in the 3-position by a carbonyl or oxime group.

However, the herbicidal properties of the prior-art compounds and their compatibility with crop plants are not entirely satisfactory.

It is an object of the present invention to provide novel, in particular herbicidally active, compounds having improved properties.

We have found that this object is achieved by the 3-heteroaryl-substituted isoxazolines of the formula I and their herbicidal action.

Furthermore, we have found herbicidal compositions which comprise compounds I and have very good herbicidal action. Moreover, we have found processes for preparing these compositions and methods for controlling unwanted vegetation using the compounds I.

Depending on the substitution pattern, the compounds of the formula I may contain one or more centers of chirality, in which case they are present as enantiomers or mixtures of diastereomers. The invention provides both the pure enantiomers or diastereomers and their mixtures.

The compounds of the formula I may also be present in the form of their agriculturally useful salts, the type of salt generally being immaterial. In general, suitable salts are the salts of those cations or the acid addition salts of those acids whose cations and anions, respectively, have no adverse effect on the herbicidal action of the compounds I.

Suitable cations are in particular ions of the alkali metals, preferably lithium, sodium and potassium, of the alkaline earth metals, preferably calcium and magnesium, and of the transition metals, preferably manganese, copper, zinc and iron, and also ammonium, where, if desired, one to four hydrogen atoms may be replaced by C₁-C₄-alkyl, hydroxy-C₁-C₄-alkyl, C₁-C₄-alkoxy-C₁-C₄-alkyl, hydroxy-C₁-C₄-alkoxy-C₁-C₄-alkyl, phenyl or benzyl, preferably ammonium, dimethylammonium, diisopropylammonium, tetramethylammonium, tetrabutylammonium, 2-(2-hydroxyeth-1-oxy)eth-1-ylammonium, di(2-hydroxyeth-1-yl)ammonium, trimethylbenzylammonium, furthermore phosphonium ions, sulfonium ions, preferably tri(C₁-C₄-alkyl)sulfonium, and sulfoxonium ions, preferably tri(C₁-C₄-alkyl)sulfoxonium.

Anions of useful acid addition salts are primarily chloride, bromide, fluoride, hydrogensulfate, sulfate, dihydrogenphosphate, hydrogenphosphate, nitrate, hydrogencarbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate, and the anions of C₁-C₄-alkanoic acids, preferably formate, acetate, propionate and butyrate.

The organic moieties mentioned for the substituents R¹-R⁷ or as radicals on aryl or heteroaryl rings are collective terms for individual enumerations of the individual group members. All hydrocarbon chains, i.e. all alkyl, haloalkyl, cyanoalkyl, alkoxy, haloalkoxy, alkylcarbonyloxy, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfonyl, alkylcarbonyl, alkoxycarbonyl, haloalkoxycarbonyl, alkylamino, dialkylamino, alkylcarbonylamino, N-alkylcarbonyl-N-alkylamino; alkoxyalkyl, alkoxyalkoxy, alkylthioalkyl, dialkylaminoalkyl and alkoxycarbonylalkyl moieties, may be straight-chain or branched. Unless indicated otherwise, halogenated substituents preferably carry one to five identical or different halogen atoms. In each case, the term “halogen” denotes fluorine, chlorine, bromine or iodine.

The 3-heteroaryl-substituted isoxazolines of the formula I can be obtained by different routes, for example by the following process:

Process A

An aldoxime of the formula VII is, via the corresponding hydroxamic acid halide of the formula VI converted into a nitrile oxide of the formula V. The nitrile oxide of the formula V reacts with an allyl alcohol of the formula IV to give a 5-hydroxymethylisoxazoline of the formula III. This is then etherified with an arylmethyl derivative of the formula II to give the 3-heteroaryl-substituted isoxazoline of the formula I:

L¹ in formula II is a nucleophilically displaceable leaving group, such as halogen (e.g. chlorine, bromine or iodine), arylsulfonyl, C₁-C₆-alkylsulfonyl, C₁-C₆-haloalkylsulfonyl, C₁-C₆-alkylsulfonyloxy or C₁-C₆-haloalkylsulfonyloxy, such as, for example, tolylsulfonyl or trifluoromethylsulfonyloxy, or another equivalent leaving group.

Hal in formula VI is halogen, preferably chlorine or bromine, with particular preference bromine.

The reaction of the 5-hydroxymethylisoxazoline of the formula III with an arylmethyl derivative of the formula II in the presence of a base to give the 3-heteroaryl-substituted isoxazoline of the formula I is usually carried out at temperatures of from 0° C. to 120° C., preferably from 10° C. to 80° C., in an inert organic solvent [cf. EP-0 334 120].

Suitable aprotic solvents are ethers, such as diethyl ether, diisopropyl ether, tert-butyl methyl ether, dioxane, anisole and tetrahydrofuran, and also dimethyl sulfoxide, dimethylformamide and dimethylacetamide, particularly preferably diethyl ether, tert-butyl methyl ether, dioxane and tetrahydrofuran.

It is also possible to use mixtures of the solvents mentioned.

Suitable bases are, in general, inorganic compounds, such as alkali metal and alkaline earth metal hydroxides, such as lithium hydroxide, sodium hydroxide, potassium hydroxide and calcium hydroxide, alkali metal and alkaline earth metal hydrides, such as lithium hydride, sodium hydride, potassium hydride and calcium hydride, alkali metal amides, such as lithium amide, sodium amide and potassium amide, alkali metal and alkaline earth metal carbonates such as lithium carbonate, sodium carbonate, potassium carbonate and calcium carbonate, moreover organic bases, for example tertiary amines, such as trimethylamine, triethylamine, diisopropylethylamine and N-methylpiperidine, pyridine, substituted pyridines, such as collidine, lutidine and 4-dimethylaminopyridine, and also bicyclic amines.

The bases are generally employed in catalytic amounts; however, they can also be employed in equimolar amounts, in excess or, if appropriate, as solvent.

The starting materials are generally reacted with one another in equimolar amounts. It may be advantageous to employ an excess of II, based on III.

Work-up and isolation of the products can be carried out in a manner known per se.

The arylmethyl derivatives of the formula II required for preparing the 3-heteroaryl-substituted isoxazolines of the formula I are known from the literature [cf. Organikum, 1979, pp. 213f., 413f.], or they can be prepared in accordance with the literature cited.

The nitrile oxides of the formula V required for preparing the 5-hydroxymethylisoxazolines of the formula III can be prepared in accordance with the literature in situ from the corresponding aldoximes of the formula VII via the stage of the hydroxamic acid halide of the formula VI [cf. Houben-Weyl, Methoden der organischen Chemie [Methods of organic chemistry], vol. E 5, 1985, p. 1591 ff. and literature cited therein], or they are known from the literature cited.

In general, the aldoxime of the formula VII is initially charged together with the allyl alcohol of the formula IV; using a halogenating agent, if appropriate with addition of base, the corresponding hydroxamic acid chloride of the formula VI is formed, and this is converted by further addition of base into the nitrile oxide of the formula V. The nitrile oxide of the formula V generated in this way then reacts with the allyl alcohol of the formula IV initially charged with the reaction mixture to give the 5-hydroxymethylisoxazoline of the formula III.

Furthermore, it is also possible to initially halogenate the aldoxime of the formula VIII to give the hydroxamic acid chloride of the formula VI, followed by addition of the allyl alcohol of the formula IV and the base. The nitrile oxide of the formula V generated in this way then reacts with the allyl alcohol of the formula IV, giving the 5-hydroxymethylisoxazoline of the formula III.

The reaction of the nitrile oxide of the formula V with an allyl alcohol of the formula IV is usually carried out at temperatures of from −30° C. to 80° C., preferably from −10° C. to 20° C., in an inert organic solvent [cf. Houben-Weyl, Methoden der organischen Chemie, Vol. E 5, 1985, 1607 ff. and literature cited therein].

Suitable solvents are aliphatic hydrocarbons, such as pentane, hexane, cyclohexane and mixtures of C₅-C₈-alkanes, aromatic hydrocarbons, such as toluene, o-, m- and p-xylene, halogenated hydrocarbons, such as methylene chloride, chloroform and chlorobenzene, ethers, such as diethyl ether, diisopropyl ether, tert-butyl methyl ether, dioxane, anisole and tetrahydrofuran, nitrites, such as acetonitrile and propionitrile, ketones, such as acetone, methyl ethyl ketone, diethyl ketone and tert-butyl methyl ketone, dimethyl sulfoxide, dimethylformamide and dimethylacetamide.

It is also possible to use mixtures of the solvents mentioned.

The starting materials are generally reacted with one another in equimolar amounts. It may be advantageous to use an excess of IV, based on V.

The reaction mixtures are worked up in a customary manner, for example by mixing with water, separating the phases and, if appropriate, chromatographic purification of the crude products. Some of the intermediates and end products are obtained in the form of viscous oils which can be freed from volatile components or purified under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, purification can also be carried out by recrystallization or digestion.

The corresponding aldoximes of the formula VII are known from the literature [cf. Houben-Weyl, Methoden der organischen Chemie, Vol. 10/4, 1968, p. 55 ff.], or they can be prepared from the corresponding aldehydes, in accordance with the literature cited.

The allyl alcohols of the formula IV required for preparing the 5-hydroxymethylisoxazolines III are known from the literature [cf. EP-514 987; Houben-Weyl, Methoden der organischen Chemie, Vol. 6/1a, 1979, p. 55 ff. and literature cited therein] or they can be prepared in accordance with the literature cited.

Process B

A nitrile oxide of the formula V reacts with an allyl derivative of the formula VIII to give a methyl isoxazoline derivative of the formula IX. This is then etherified with an arylmethyl alcohol of the formula X to give the 3-heteroaryl-substituted isoxazoline of the formula I:

L² in the formulae VIII and IX is a nucleophilically displaceable leaving group, such as halogen (e.g. chlorine, bromine or iodine), C₁-C₆-alkylsulfonyloxy or C₁-C₆-haloalkylsulfonyloxy, such as, for example, trifluoromethylsulfonyloxy, or another equivalent leaving group.

The reaction of the methylisozoline derivative of the formula IX with an arylmethyl alcohol of the formula X is carried out analogously to the reaction of the 5-hydroxymethylisoxazoline of the formula III with an arylmethyl derivative of the formula II in process A.

The arylmethyl alcohols of the formula X required for preparing the 3-heteroaryl-substituted isoxazolines of the formula I are known to the person skilled in the art or can be prepared by reactions known from the literature.

The preparation of the methylisoxazoline derivatives of the formula IX from nitrile oxides of the formula V and allyl derivatives of the formula VIII is carried out analogously to the preparation of the 5-hydroxymethylisoxazolines of the formula III in process A.

Furthermore, it is possible to prepare the methylisoxazoline derivatives of the formula IX from 5-hydroxymethylisoxazolines of the formula III:

The conversion of the 5-hydroxymethylisoxazolines into methylisoxazoline derivatives of the formula IX is usually carried out at temperatures of from −20° C. to the reflux temperature of the reaction mixtures in question, in an inert solvent.

Suitable solvents are aliphatic hydrocarbons, such as pentane, hexane, cyclohexane and mixtures of C₅-C₈-alkanes, aromatic hydrocarbons, such as toluene, o-, m- and p-xylene, halogenated hydrocarbons, such as methylene chloride, chloroform and chlorobenzene, ethers, such as diethyl ether, diisopropyl ether, tert-butyl methyl ether, dioxane, anisole and tetrahydrofuran. It is also possible to use mixtures of the solvents mentioned.

Suitable activating agents are, for example, halogenating agents, such as thionyl chloride, phosgene, diphosgene, triphosgene, oxalyl chloride, thionyl bromide, oxalyl bromide, or, for example, alkylsulfonyl chlorides, such as, for example, methylsulfonyl chloride, or haloalkylsulfonyl chlorides, such as, for example, trifluoromethylsulfonyl chloride.

The starting materials are generally reacted with one another in equimolar amounts. It may be advantageous to employ an excess of activating agent.

The allyl derivatives of the formula VIII are known to the person skilled in the art or can be prepared, for example, from the allyl alcohols of the formula IV, analogously to the conversion of III into IX.

Process C

An allyl alcohol of the formula IV is converted with arylmethyl derivative of the formula II into an arylmethyl allyl ether of the formula XI. This then reacts with a nitrile oxide of the formula V to give the 3-heteroaryl-substituted isoxazolines of the formula I:

L¹ in formula II is a nucleophilically displaceable leaving group, such as halogen (e.g. chlorine, bromine or iodine), aryl-, C₁-C₆-alkylsulfonyl, toluolsulfonyl, C₁-C₆-haloalkylsulfonyl, C₁C₆-alkylsulfonyloxy or C₁-C₆-haloalkylsulfonyloxy (such as e.g. or trifluoromethylsulfonyloxy), or another equivalent leaving group.

The reaction of the arylmethyl allyl ethers of the formula XI with a nitrile oxide of the formula V to give the 3-heteroaryl-substituted isoxazolines of the formula I is carried out analogously to the reaction of the nitrile oxide of the formula V with an allyl alcohol of the formula IV in process A.

The 3-heteroaryl-substituted isoxazolines of the formula I and their agriculturally useful salts are suitable, both in the form of isomer mixtures and in the form of the pure isomers, as herbicides. The herbicidal compositions comprising compounds of the formula I control vegetation on non-crop areas very efficiently, especially at high rates of application. They act against broad-leaved weeds and harmful grasses in crops such as wheat, rice, maize, soya and cotton without causing any significant damage to the crop plants. This effect is mainly observed at low rates of application.

Depending on the application method used, the compounds of the formula I or the herbicidal compositions comprising them can additionally be employed in a further number of crop plants for eliminating undesirable plants. Examples of suitable crops are the following:

Allium cepa, Ananas comosus, Arachis hypogaea, Asparagus officinalis, Beta vulgaris spec. altissima, Beta vulgaris spec. rapa, Brassica napus var. napus, Brassica napus var. napobrassica, Brassica rapa var. silvestris, Camellia sinensis, Carthamus tinctorius, Carya illinoinensis, Citrus limon, Citrus sinensis, Coffea arabica (Coffea canephora, Coffea liberica), Cucumis sativus, Cynodon dactylon, Daucus carota, Elaeis guineensis, Fragaria vesca, Glycine max, Gossypium hirsutum, (Gossypium arboreum, Gossypium herbaceum, Gossypium vitifolium), Helianthus annuus, Hevea brasiliensis, Hordeum vulgare, Humulus lupulus, Ipomoea batatas, Juglans regia, Lens culinaris, Linum usitatissimum, Lycopersicon lycopersicum, Malus spec., Manihot esculenta, Medicago sativa, Musa spec., Nicotiana tabacum (N. rustica), Olea europaea, Oryza sativa, Phaseolus lunatus, Phaseolus vulgaris, Picea abies, Pinus spec., Pisum sativum, Prunus avium, Prunus persica, Pyrus communis, Ribes sylvestre, Ricinus communis, Saccharum officinarum, Secale cereale, Solanum tuberosum, Sorghum bicolor (S. vulgare), Theobroma cacao, Trifolium pratense, Triticum aestivum, Triticum durum, Vicia faba, Vitis vinifera and Zea mays.

In addition, the compounds of the formula I may also be used in crops which tolerate the action of herbicides owing to breeding, including genetic engineering methods.

The compounds of the formula I, or the herbicidal compositions comprising them, can be used for example in the form of ready-to-spray aqueous solutions, powders, suspensions, also highly-concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for broadcasting or granules, by means of spraying, atomizing, dusting, broadcasting or watering. The use forms depend on the intended aims; in any case, they should ensure a very fine distribution of the active compounds according to the invention.

The herbicidal compositions comprise a herbicidally effective amount of at least one compound of the formula I or an agriculturally useful salt of I and auxiliaries customary for formulating crop protection agents.

Essentially, suitable inert auxiliaries include: mineral oil fractions of medium to high boiling point, such as kerosene and diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, e.g. paraffins, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, alkylated benzenes and their derivatives, alcohols such as methanol, ethanol, propanol, butanol and cyclohexanol, ketones such as cyclohexanone, strongly polar solvents, e.g. amines such as N-methylpyrrolidone, and water.

Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, the substrates, either as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is also possible to prepare concentrates consisting of active substance, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, which are suitable for dilution with water.

Suitable surfactants (adjuvants) are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, e.g. ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl- and alkylarylsulfonates, alkyl sulfates, lauryl ether sulfates and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols, and also of fatty alcohol glycol ethers, condensates of sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene, or of the naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenyl polyglycol ether or tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers or polyoxypropylene alkyl ethers, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignosulfite waste liquors or methylcellulose.

Powders, materials for broadcasting and dusts can be prepared by mixing or grinding the active substances together with a solid carrier.

Granules, e.g. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active compounds to solid carriers. Solid carriers are mineral earths, such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate and ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders, or other solid carriers.

The concentrations of the compounds of the formula I in the ready-to-use preparations can be varied within wide ranges. In general, the formulations comprise from about 0.001 to 98% by weight, preferably 0.01 to 95% by weight of at least one active compound. The active compounds are employed in a purity of from 90% to 100%, preferably from 95% to 100% (according to the NMR spectrum).

The production of such preparations is illustrated by the following formulation examples:

-   I. 20 parts by weight of an active compound of the formula I are     dissolved in a mixture consisting of 80 parts by weight of alkylated     benzene, 10 parts by weight of the adduct of 8 to 10 mol of ethylene     oxide to 1 mol of oleic acid N-monoethanolamide, 5 parts by weight     of calcium dodecylbenzenesulfonate and 5 parts by weight of the     adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring     the solution into 100,000 parts by weight of water and finely     distributing it therein gives an aqueous dispersion which comprises     0.02% by weight of the active compound of formula I. -   II. 20 parts by weight of an active compound of the formula I are     dissolved in a mixture consisting of 40 parts by weight of     cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight     of the adduct of 7 mol of ethylene oxide to 1 mol of isooctylphenol     and 10 parts by weight of the adduct of 40 mol of ethylene oxide to     1 mol of castor oil. Pouring the solution into 100,000 parts by     weight of water and finely distributing it therein gives an aqueous     dispersion which comprises 0.02% by weight of the active compound of     formula I. -   III. 20 parts by weight of an active compound of the formula I are     dissolved in a mixture consisting of 25 parts by weight of     cyclohexanone, 65 parts by weight of a mineral oil fraction of     boiling point 210 to 280° C. and 10 parts by weight of the adduct of     40 mol of ethylene oxide to 1 mol of castor oil. Pouring the     solution into 100,000 parts by weight of water and finely     distributing it therein gives an aqueous dispersion which comprises     0.02% by weight of the active compound of formula I. -   IV. 20 parts by weight of an active compound of the formula I are     mixed thoroughly with 3 parts by weight of sodium     diisobutylnaphthalenesulfonate, 17 parts by weight of the sodium     salt of lignosulfonic acid from a sulfite waste liquor and 60 parts     by weight of pulverulent silica gel, and the mixture is ground in a     hammer mill. Finely distributing the mixture in 20,000 parts by     weight of water gives a spray mixture which comprises 0.1% by weight     of the active compound of formula I. -   V. 3 parts by weight of an active compound of the formula I are     mixed with 97 parts by weight of finely divided kaolin. This gives a     dust which comprises 3% by weight of the active compound of formula     I. -   VI. 20 parts by weight of an active compound of the formula I are     mixed intimately with 2 parts by weight of calcium     dodecylbenzenesulfonate, 8 parts by weight of fatty alcohol     polyglycol ether, 2 parts by weight of the sodium salt of a     phenol/urea/formaldehyde condensate and 68 parts by weight of a     paraffinic mineral oil. This gives a stable oily dispersion. -   VII. 1 part by weight of an active compound of the formula I is     dissolved in a mixture consisting of 70 parts by weight of     cyclohexanone, 20 parts by weight of ethoxylated isooctylphenol and     10 parts by weight of ethoxylated castor oil. This gives a stable     emulsion concentrate. -   VIII. 1 part by weight of an active compound of the formula I is     dissolved in a mixture of 80 parts by weight of cyclohexanone and 20     parts by weight of Wettol® EM 31 (=nonionic emulsifier based on     ethoxylated castor oil). This gives a stable emulsion concentrate.

The compounds of the formula I or the herbicidal compositions can be applied pre- or post-emergence. If the active compounds are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of the spraying equipment, in such a way that they come into contact as little as possible, if at all, with the leaves of the sensitive crop plants, while the active compounds reach the leaves of undesirable plants growing underneath, or the bare soil surface (post-directed, lay-by).

The application rates of the compound of the formula I are from 0.001 to 3.0, preferably from 0.01 to 1.0 kg/ha of active substance (a.s.), depending on the control target, the season, the target plants and the growth stage.

To widen the activity spectrum and to achieve synergistic effects, the 3-heteroaryl-substituted isoxazolines of the formula I may be mixed with a large number of representatives of other herbicidal or growth-regulating active compound groups and are applied concomitantly. Suitable components for mixtures are, for example, 1,2,4-thiadiazoles, 1,3,4-thiadiazoles, amides, aminophosphoric acid and its derivatives, aminotriazoles, anilides, (hetero)aryloxyalkanoic acids and their derivatives, benzoic acid and its derivatives, benzothiadiazinones, 2-(hetaroyl/aroyl)-1,3-cyclohexanediones, heteroarylaryl ketones, benzylisoxazolidinones, meta-CF₃-phenyl derivatives, carbamates, quinolinecarboxylic acid and its derivatives, chloroacetanilides, cyclohexenone oxime ether derivatives, diazines, dichloropropionic acid and its derivatives, dihydrobenzofurans, dihydrofuran-3-ones, dinitroanilines, dinitrophenols, diphenyl ether, dipyridyls, halocarboxylic acids and their derivatives, ureas, 3-phenyluracils, imidazoles, imidazolinones, N-phenyl-3,4,5,6-tetrahydrophthalimides, oxadiazoles, oxiranes, phenols, aryloxy- and heteroaryloxyphenoxypropionic esters, phenylacetic acid and its derivatives, 2-phenylpropionic acid and its derivatives, pyrazoles, phenylpyrazoles, pyridazines, pyridinecarboxylic acid and its derivatives, pyrimidyl ethers, sulfonamides, sulfonylureas, triazines, triazinones, triazolinones, triazolecarboxamides and uracils.

It may furthermore be advantageous to apply the compounds of the formula I, alone or else concomitantly in combination with other herbicides, or in the form of a mixture with other crop protection agents, for example together with agents for controlling pests or phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions, which are employed for treating nutritional and trace element deficiencies. Non-phytotoxic oils and oil concentrates may also be added.

USE EXAMPLES

The herbicidal activity of 3-heteroaryl-substituted isoxazolines of the formula I was demonstrated by the following greenhouse experiments:

The cultivation containers used were plastic flower pots containing loamy sand with approximately 3.0% of humus as the substrate. The seeds of the test plants were sown separately for each species.

For the pre-emergence treatment, directly after sowing the active compounds, which had been suspended or emulsified in water, were applied by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with transparent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants, unless this was adversely affected by the active compounds. The application rate for the post-emergence treatment was 3.0 kg/ha a.s. (active substance).

For the post-emergence treatment, the test plants were first grown to a height of from 3 to 15 cm, depending on the plant habit, and only then treated with the active compounds which had been suspended or emulsified in water. The test plants were for this purpose either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to treatment.

Depending on the species, the plants were kept at 10-25° C. or 20-35° C. The test period extended over 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.

Evaluation was carried out using a scale from 0 to 100. 100 means no emergence of the plants, or complete destruction of at least the above-ground parts and 0 means no damage, or normal course of growth.

The plants used in the greenhouse experiments were of the following species: Scientific name Common name Abutilon theophrasti velvet leaf Avena fatua wild oat Lolium multiflorum Italian ryegrass Setaria italica foxtail millet

At application rates of 3.0 kg/ha, the compounds 3.16, 3.17, 3.27, 3.36, 4.29 and 4.38 showed very good preemergence activity in the harmful plants Solium multiflorum and Setaria italica.

At application rates of 3.0 kg/ha, the pre-emergence activity of compound 4.1 on the harmful plants Lolium multiflorum and Setaria italica is very good.
